Recombinant Human SEMA3A (N-6H

Recombinant Human SEMA3A (N-6His-Flag) (CP98)

产品说明(Description)

Recombinant Human Semaphorin 3A is produced by our Mammalian expression system and the target gene encoding Lys26-Phe546 is expressed with a 6His-Flag tag at the N-terminus. 

Accession #: Q14563

Known as: Synonyms: Semaphorin III; SEMA3A; SEMAD; Hsema-I; SEMA1; SemD; Semad; coll-1 ; Hsema-III; Sema III

 

制剂(Formulation)

Lyophilized from a 0.2 μm filtered solution of PBS, 5% Trehalose, pH 7.4.

 

质量控制(Quality Control)

 

Purity:        Greater than 95% as determined by reducing SDS-PAGE.    

Endotoxin: Less than 0.1 ng/µg (1 EU/µg) as determined by LAL test.

 

复溶(Reconstitution)

Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
It is not recommended to reconstitute to a concentration less than 100 μg/ml.
Dissolve the lyophilized protein in distilled water.
Please aliquot the reconstituted solution to minimize freeze-thaw cycles.    

 

保存(Storage)

Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.Reconstituted protein solution can be stored at 4-7°C for 2-7 days.Aliquots of reconstituted samples are stable at < -20°C for 3 months.     

 

背景(Background)

emaphorin-3A is a secreted protein which belongs to the semaphorin family. Semaphorins are a family of secreted and cell-bound signaling molecules defined by the presence of a common 500 aa Sema domain.This protein can function as either a chemorepulsive agent, inhibiting axonal outgrowth, or as a chemoattractive agent, stimulating the growth of apical dendrites. In both cases, the protein is vital for normal neuronal pattern development. Increased expression of this protein is associated with schizophrenia and is seen in a variety of human tumor cell lines.
